Wednesday Video plenary status review

A Video subgroup plenary was held 11:00-13:00 on Wednesday. Reports of BoGs were given as follows:

MPEG-7 Visual:

• 
  FDIS of new edition
  
• 
  Document on using descriptors for scene classification
  

CDVS:

• 
  New part 14 for SW/Conf/TM
  
• 
  Awareness event planned for Warsaw
  
• 
  Software newly structured, outputs information about matching process, acceleration of feature point detection, Matlab interface, all uses BSD header
  
• 
  Implementation on mobile device demonstrated, coding/decoding requires unexpectedly long time (to be further investigated), matching is acceptable
  
• 
  FDIS preparation: One comment points out that resampling is not sufficiently specified (could have consequences on conformance?)
  
• 
  DoC to be presented Friday
  

IVC:

• 
  Reviewed all input documents
  
• 
  Visual testing planned for Thursday, 9 volunteers needed
  
• 
  For LD, all bit rates are in the margin of +/- 3%. For RA
  
• 
  This seems to allow making an assessment (qualitatively) whether within the last 9 month IVC has reached a level of visual quality that would be comparable to the other codecs
  
• 
  Considered for new ITM: Lagrangian optimization (non-normative); stronger deblocking filter covered by expired patent of 1993; improvement of transform, add 4x4 transform for intra for which a patent has been applied for by proponents.
  
• 
  Improvement of WD text,
  

RVC:

• 
  Review of PDAM Thu 11:00 (Stuttgart)
  
• 
  White paper draft has been delivered
  

CICP:

• 
  Alexis Tourapis and Teruhiko Suzuki took responsibility for preparing 23001-8/DAM2 which was later presented during the Thursday plenary.
  

VCB:

• 
  DoC on software and conformance prepared.
  
• 
  Note: Since the AVC conformance was used as a kind of starting point for this, the same problems pointed out by US may apply to Amd.6 of Conformance. In Amd.44, it is planned to resolve them for the case
